Residual Heat - BMW 2009 X5 Owner's Manual

By pressing the button repeatedly, you can
request three operating modes:
>
LED off: outside air flows in continuously.
> Left LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
> Right LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirculated-air mode and
increase the air volume if necessary.
The recirculated-air mode should not be used
without interruption over an extended period of
time, as the air quality inside the vehicle deteri-
orates continuously.<
